High Dynamic Range - HDR Images

Creating you own HDR Images

Creating HDR images may sound complex on the surface but it is not as complicated as you might think.  In this article I will attempt to simplify this topic as much as possible so that you can gain a basic understanding of how to create HDR images and enjoy this relatively new and exciting image technology.

Overview

Basically, HDR images are composed from at least 3 separate exposures and then combined together in a photo processing program such as Photoshop.  results.There are several very good products on the market that are specifically designed for this and I'll explain more about that later.

Generally 3 exposures are all that is needed for good HDR results and that is what I will be describing in this article.  The 3 exposures are comprised of a "normal", "under exposed" and "over exposed" images.  Your camera will be doing most of the work in creating these exposures so it is pretty straight forward to create the exposures.

Equipment required for creating HDR images need not be expensive or elaborate.  You'll need any basic camera, typically a DLSR, that has the ability to change exposure values in increments of at least 1/3 stops.  In addition, a tripod is pretty much mandatory because the camera has to be stable enough so there is no movement in between the 3 exposures.  A shutter release cable is very helpful also but not absolutely necessary.  You can forego the shutter release cable by using the camera's built-in timer mode.
